During the dark times after the fall of Rome, the Saxon's became a unifying force as an enemy of the young Frankish Kingdom in France. This lead gradually to their conquest, the crowning of the first Holy Roman EmperorCharlemagne and the establishment of various principalities in the region with names derived from the Saxons. These political names would drift south and east over the centuries, as dynastic political power moved south and east toward larger cities with natural resources—so in effect the 'German Princes' inherited estates gravitated eastwards as well, so much so, the region known as Saxony in it's day, effectively migrated to the current Federated State (on the other) side of Today's Germany, once just a part of the larger Saxony of the 1600's.

Two other German states (both located more closely to the tribal ancestral homelands as reported by Roman sources) are also named after the Saxons, Saxony-Anhalt (Sachsen-Anhalt—generally the western part of the Saxony of the Holy Roman Empire) and Lower Saxony (Niedersachsen, encompassing the general area the Romans reported the Tribe occupied)—the latter name's 'Lower' term being a (now dated) reference to the low lying plains region as related to the historiographical term Low Countries, which abuts the region on the West.
